Abstract: A housing structure for a sound generator includes a base portion having a separation wall; a case portion that defines a first space with the base portion; a covering portion that defines a second space with the base portion; a frame portion that projects toward the second space from the separation wall; a screen wall disposed on an outer side of the frame portion to define a groove between the screen wall and the frame portion; and a screen board arranged on an inner side of the screen wall. The screen board is distanced from the frame portion and the screen wall.

Abstract: Sound generated by a sound emitting unit passes through a first sound passage defined between a first shielding board and a shielding cylinder and a second sound passage defined between a second shielding board and the shielding cylinder, and is emitted outside from a sound emitting hole defined in at least one of a case and a cover. The second shielding board and the shielding cylinder shield a space between the sound emitting hole and the first sound passage when the first sound passage is seen from the sound emitting hole.

Abstract: A non-immunosuppressive pipecolic acid derivative having an affinity for FKBP-type immunophilins is provided for inducing chondrogenic differentiation. Composition containing such compounds is also disclosed.

Abstract: A compound of the formula (I): wherein R1 is hydrogen, halogen, carbamoyl, cyano, formyl, or lower alkyl optionally substituted with halogen, amino or a protected amino; R2 is hydrogen, halogen, cyano or lower alkoxy; R3 is phenyl or pyridyl, each of which is substituted with lower alkoxy; and R4 is lower alkoxy; provided that either R1 or R2 is hydrogen, then the other is other than hydrogen, or its salts, which are useful as a medicament.

Abstract: Chondrogenic differentiations is induced by administering a macrocyclic lactone to mammals to prevent or treat damage to cartilage.

Abstract: Film carriers for mounting electronic components such as semiconductor chips thereon have lead portions plated with a tin or tin alloy layer and further with an indium layer. The tin or tin alloy layer is 0.1-3 .mu.m thick and the indium layer 0.01-2 .mu.m thick. Alternatively, the leads have a tin or tin alloy plated portion having an indium diffusion layer, with an indium content of 0.2-50 wt %. The carriers are manufactured by a method which comprises plating the leads with tin or a tin alloy and then with indium, with or without heat treatment at 50.degree.-150.degree. C. to form an indium diffusion layer in the tin or tin alloy coating. Plating is done by electroless plating.
